Flat display panel

Abstract

A flat display panel has a first substrate, a second substrate, a black matrix pattern being disposed on a surface of the second substrate in a non-display area, and a brightness enhancement sheet being disposed on a surface of the second substrate opposite to the first substrate; wherein the area ratio of the black matrix pattern to its corresponding pixel region is between 70% and 95%.

1 . A flat display panel comprising: 
 a first substrate;    a second substrate opposing to the first substrate and divided into a plurality of pixel regions, each pixel region having a display area and a non-display area;    a black matrix pattern disposed on each non-display area of the second substrate; and    a brightness enhancement sheet disposed on a surface of the second substrate opposite the first substrate,    wherein the area ratio of the black matrix pattern to the pixel region is between about 70% and about 95% in each pixel region.    
   
   
       2 . The flat display panel of  claim 1 , wherein the black matrix pattern is disposed on a surface of the second substrate facing the first substrate.  
   
   
       3 . The flat display panel of  claim 1 , further comprising a color filter pattern disposed on a surface of the second substrate facing the first substrate, the color filter pattern being disposed on each display area.  
   
   
       4 . The flat display panel of  claim 1 , wherein the black matrix pattern is disposed on a surface of the second substrate opposite the first substrate.  
   
   
       5 . The flat display panel of  claim 1 , further comprising a color filter pattern disposed on a surface of the second substrate opposite the first substrate, the color filter pattern being disposed on each display area.  
   
   
       6 . The flat display panel of  claim 1 , wherein the brightness enhancement sheet is attached to the second substrate.  
   
   
       7 . The flat display panel of  claim 1 , wherein the brightness enhancement sheet is formed on the second substrate.  
   
   
       8 . The flat display panel of  claim 1 , wherein the surface of the second substrate opposite the first substrate is a display surface.  
   
   
       9 . The flat display panel of  claim 1 , further comprising an organic light emitting device positioned in each pixel region.
